Bridgestone ED78 is great but doesn't last long. Honestly for durability the D908 is tops, but it doth suck in sand. I was thinking about taking a Maxxis Desert IT next time maybe. I have an SE 2.5" rear wheel...which this Baja 990 ought to have come with imho.

Funny that the 908 is the predominate tire choice for the Dakar rally, not that there is much sand there.

I think what sux more is the 500 lb bike in the sand. You are asking a lot of any knobby because of that.
